Specification of Letters Patent. Patented Sept 21, 1915;v

Application filed September 24, 1914. Serial No, 863,250.

T0 @ZZ whom t may concern: i

Be itknown that I, EDWARD E. VAKEFIELD', a citizen of the United States,and resident of the city of Providence, inthe county of Providence andState of Rhode Island, have invented certain new and useful Improvementsin Lacing-Stud-Setting Machines, of

lwhich the following yis a specification.

matically adjusting the cutting lmembers relative to each other tocompensate for wearon said members. n

This invention .is an improvement oniny co-pending application SerialNo. 845,939.

It is found in practice that where the strip of tape is fed to themachine and cut and severed at predetermined intervals that unless thetape is completely severed at each Acutting operation the Vuiiseveredthreads hold the parts-together and prevent the proper placing andpositioning of the partially severed pieces onto the upper, and it isalso found that the reason for such imperfect work 'is'due largely tothe wearing of the cutting surfaces of the yshearing plates. obviatethis difficulty and insure a complete severing of the tape at eachcuttingoperation, I have provided simple and effective means intheoperating parts to automatically compensate for this wearing to keep thecutter plates always in proper working i relation with each other.

lVith these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out inthe appended claims. y

In the accompanying drawings: Figure l1-. is a side elevationillustrating a portion of the mechanism for feeding the shoe upper,means for feeding the reinforcing tape, and means for severing the` sameintopredeternilined lengths, to which mechanism is attached my improvedautomatic adjustment for the severing plates: Fig. 2- is 4a' plan viewof a portion of theinechanisni TOl showing means in the .presser footblock for adjusting the relative position of the cutter plates. Fig, 3-is a side elevation showing the means for setting the presser foot alsoshowing'the block slidably mounted in said presser foot. F ig. t is anenlarged sectional view showing means for automatically. adjusting thecutter plates relative to each other. Fig.A 5- is a view of the innerside of a shoe upper showing the tape as having been positioned to serveas a backing or reinforcement for the studs when riveted thereto. Fig.6-4 is a greatly enlarged edge view of the workshowing the lacing studsin the form of hooks and eyelets as set into a shoe upper and myvreinforcing tape in position to serve as a support or backing Vforthestuds yifivetedin position in the work.

. In myco-pending application' above referred to have -described'andshown the mechanism to which my present improved mechanism is attachedand by which it is f Aoperated. I have also set forth thefact that theterm lacingstud used throughout the specification and claims, refers toand includes both the eyelet and lacing hook formation ordinarilyemployed in shoe uppers,

force to my present patent application. I have herein shown anddescribed only sutli- .cient mechanism to illustrate my presentinvention. I Y n y Y Y In the accompanying,drawings 10 designates aportion of the carriage in which is 4mounted the punch spindle ll andthe spring lmounted the cutter 2G for severing the reinforcing tape.

The guide block lll connected to the spindle 11 also serves to carry oneor vmore needles orspurs 19, which are arand the same is intended toapply with equal ranged to engage :the tape for the purpose of causingitto advance with the feedinginovement ofthe carriage head, which is`fully described in my above mentioned patent application. The usualpresser foot 20 which is raised and lowered through the rod 2l vbymeans(not shown) is provided with ways .22 in which slides the block 2.3.This iblock is slotted at'Ql longitudinally tore- Acei've the tape 16which passes therethrough and the forward face of this block is providedwith a cutter plate 25 against which works the second verticallyreciprocable cutter plate 26 carried by the punch' spindle ll. Thisblock is also provided with vertical holes 27 through which needles 19pass on their way into and out of engagement with the reinforcing tape.

The essential feature' of my improved invention is the provision ofmeans for permitting an adjustment of the cutter plates relative to eachother so as to compensate for 'wear' between them. One means for simply'and practically accomplishing this purpose is herein shown andillustrated, which is that of cutting away or removing the middleportion of the upper face of this 'block 23 into which recessed portionis slida'bly mounted a socket plate 28 connected rigidly to the end ofspindle 12'. One end of this plate extends out over the rear end of theblock and is. provided with a downwardly extending finger 29 throughwhich a screw' 30 is passed and threaded into the rear wall of saidblock and between the block and the flangev is inserted a tensionspringk 31 which exerts a forward pressure upon the block to maintainits frpnt cutter plate 25 always in contact or inoperative relation tothe reciprocating cutter plate 26 so as to take up or to compensate forany wear of these plates and to keep the cutters in operative relationto produce effective work and sever the tape at each downward stroke ofthe punch spindle. v

The tape 16 is ledfrom the reel (not shown) through a suitable guide 35sup'- p'ortedfrom the arm 36 in which guide a tension spring 37 ismounted to prevent the Vtape from receding or moving backward during thereturn stroke of the feeding mechanism. From this guide the tape is ledvthrough the aperture 24 in the guide block 23 above the engagingsurface of the presser foot and over the cutting edge of the cutterplate When the punch spindle descends it' carries with it the knifeplate 26 which slides down across the face of the cutter plate 25 andsevers the portions 34 of the tape which extends through the block 23.rlhe 'downwardmovement 'of this spindle 1l a'lso causes the punch 15 Atoengage land carry the severed portions of the tapel down against theshoe upper or work b and to punch' a hole through the tape and alsovthrol'igh the work to receive the stud. The work is neXt advancedbringing the punched holes into position to receive the stud which ispassed through said holes in both the upper and tape and riveted inposition over the piece of tape as fully described in said cmeendingapplication. 1 After the stud has been set the spindle ll is raised,withdrawing the spu'rsl.) yand knife plate 26 from enga gement with thetape and the head is then carried to the right back into positionillustrated in Fig. l and this cycle of operations is repeated in thesetting of each stud into the work.

I have shown and described one form of mechanism for automaticallycompensating for the wearof the cutting members, but any means which maybe used in conjunction with the feeding and cutting the tape andconnecting the same to the shoe upper for accomplishing the automaticadjustment of the kcutting members will fall within the spirit and scopeof my invention.

I claim:
